Abstract: The object of the invention is to detect a concentration of a SOx included in an exhaust gas of an internal combustion engine easily and accurately by a limiting current type sensor. The invention relates to a SOx concentration detection device of the engine having a limiting current type sensor. The device of the invention comprises a detecting part for detecting the concentration of the SOx included in the exhaust gas by using an output current of the sensor while lowering a voltage applied to the sensor from a predetermined voltage.
